An intermediate deviceA includes a transfer unitthat transfers a request including data to be transmitted from a localto a remote, and a generation unitthat generates a pseudo-response to the request and returns the pseudo-response to the local. The intermediate deviceB includes a discard unitthat discards a response to the request from the remote. An intermediate deviceB includes a generation unitthat generates a pseudo-request based on an initial request for requesting data transmission from the localto the remoteand transmits the pseudo-request to the remote, and a transfer unitthat transfers a response including data to be transmitted from the remoteto the local. The intermediate deviceA includes the discard unitthat discards a subsequent request from the local

Intermediate apparatus, communication method, and program

A communication system includes a plurality of computing machinesandconnected to an optical network, in which the optical network includes a main signal communication pathand a control communication path. Each of the computing machinesandincludes a control unitthat sets a remote direct memory access (RDMA) communication path, and a communication unitthat transmits a setting request including setting information of the RDMA communication path set by the control unitand setting information for setting the main signal communication pathto a computing machine of an access destination via the control communication path; and a main signal transmitting/receiving unitthat establishes the main signal communication pathbased on the setting information of the main signal communication path

Communication system, computing machine, communication method and program

This communication system comprises a plurality of computersthat each comprise: an optical transport path control unitthat adjusts the number of optical transport paths between the computer itself and a connection target computer and that sets the adjusted number of optical transport paths; a remote direct memory access (RDMA) communication unitthat, in accordance with the number of optical transport pathsannounced from the optical transport path control unit, chunks data that is to be transferred to the connection target computer; and an RDMA control unitthat sets RDMA communication paths the number of which is the same as the number of the optical transport pathspursuant to an instruction from the RDMA communication unit

The communication apparatus includes: a processing device that processes communication data to be transmitted to and received from a partner apparatus; a transmission unit that transmits the communication data to the partner apparatus; an internal state measurement unit that measures a state related to transmission of the communication data between the processing device and the transmission unit and a determination unit that determines a communication mode in communication with the partner apparatus from the state. The transmission unit transmits the communication data to the partner apparatus in the determined communication mode.
